The size of sediment is defined by the size of the particles that make up the sediment. The largest sediment size is called a boulder. Boulders have a diameter that is larger than 256 millimeters (about 10 inches). Cobbles are the next largest sediment, they are 64 - 256 mm in diameter (about 3-10 inches).
However, two days later, 75,000 Allied troops were trapped by the Japanese and forced to surrender. The next day, the Bataan Death March began. Of those who survived to reach the Japanese prison camp near Cabanatuan, few lived to celebrate U.S. General Douglas MacArthurâs liberation of Luzon in 1945.
The Bataan Memorial Death March Marathon is a challenging loop-style race through the high desert terrain of White Sands Missile Range. Most of the course is dirt road or trail, with some sections being sandy, dusty, and all-around tough desert terrain. The course is mostly flat to mile 7, where runners are then confronted with a 6-mile 1200' climb. The last 13 miles are mostly downhill or flat with only a couple gentle rolling inclines.
